  • Publication number: 20130065358
    Abstract: The invention concerns the production of poly(arylene-vinylenes) and related polymers whose polymerization is triggered photochemically. For that purpose, the low molecular starting materials are firstly cooled to temperatures which are so low that in fact their activation into mostly chinoid intermediate stages (the “active” monomer) occurs; the thermally induced polymerization, however, either does not occur or barely takes place at all. The polymerization is instead triggered in a separate step by means of electromagnetic radiation of a suitable wavelength—either using the absorption behavior of the low-molecular starting compounds/the monomers, or mediated by means of photoinitiators and/or sensitizers. By way of example, with this method a display is suitable to be coated with poly(arylene-vinylenes). The monomer is hereby deposited. The polymer is subsequently produced in a photo-induced manner. The remaining monomer is washed out. The process takes place at low temperatures.

  • Patent number: 8293957
    Abstract: Described are oligotetracenes of formula I which may either be unsubstituted or carry one or more substituents R and R? which are selected from the group comprising halogen, CN, alkyl or alkoxy radicals containing 1 to 18 carbon atoms, aryl radicals containing up to 10 carbon atoms which may also contain one or more heteroatoms, and/or fluorinated or perfluorinated alkyl or alkoxy radicals containing 1 to 18 carbon atoms, where n is an integer from 1 to 20, preferably 1 to 6, very particularly preferably 1 or 2, and X stands for a single bond, an alklyene group containing 1 to 6 carbon atoms, a hydrocarbon chain having one or more conjugated double bonds, an aryl group, or a system composed of one or more condensed aromatic rings. In the oligotetracenes according to the invention, one or more of the condensed aromatic six-atom rings may be substituted by a five-atom ring which may also contain a heteroatom.

  • Publication number: 20040145077
    Abstract: The present invention relates to a process for preparing mixture from a large number of components, the concentrations of the components used being capable of continuous variation over prescribed ranges in a very simple manner. For this, the mixtures are continuously prepared in a mixing assembly and continuously converted into a form which can be subjected to further processing. By way of example, the invention may be used for producing substance libraries for high-throughput screening in the plastics industry, in particular of mixtures of polymers with one another and of mixtures of polymers with added materials.
